Variety of dicentra plant named &#39;Red Fountain&#39;

ABSTRACT

A new and distinct  Dicentra peregrina×eximia  plant named ‘Red Fountain’ with dark burgundy flowers, good vigor, a compact habit and long flowering period.

BOTANICAL CLASSIFICATION

Dicentra peregrina×eximia

VARIETAL DENOMINATION

‘Red Fountain’

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Dicentra peregrina×eximia known by the varietal name ‘Red Fountain’. The new variety was discovered in Hokkaido, Japan in May of 2004. The new variety has been asexually reproduced via tissue culture or cuttings, and the first date of asexual reproduction was in February of 2005 in Hokkaido, Japan. The new variety is the result of a planned breeding program cross between an unpatented, unnamed Dicentra peregrina plant (female parent) and an unpatented, unnamed Dicentra eximia plant (male parent). The purpose of the breeding program was to develop new varieties that exhibit improvements in vigor and longer flowering periods. The new variety exhibits similar form and foliage to both parents, but does have a more improved vigor, more flowers, and a longer flowering period than both parents. ‘Red Fountain’ exhibits similar foliage, habit, and vigor to Dicentra peregrina×eximia ‘Candy Hearts’ (U.S. Plant Pat. No. 14,692), but has a different flower color than ‘Candy Hearts’. The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations. The following characteristics distinguish ‘Red Fountain’ from other varieties known to the breeder:

-   -   1. Compact, more upright habit;     -   2. Good vigor with strong growth;     -   3. Strong, more rhizomatous root system; and     -   4. Long flowering period from late April until September.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, with the color being as nearly true as is possible with color illustrations of this type:

FIG. 1 is a close up view of the blossoms of the new variety;

FIG. 2 is a view of a field of the new variety

FIG. 3 is a close-up view of the blossoms of the new variety; and

FIG. 4 is a close up view of the foliage of the new variety.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new cultivar grown outside in the open ground with no extra fertilizer in The Netherlands. The color readings were taken in The Netherlands in natural daylight. Plants of the new cultivar were approximately four months old when described as the plugs were planted in May and the measurements were taken in early September. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
